They could recognize this literally by hearing a voice from God, who had chosen them for this profession. Over time, the word became secularized, referring to any work or study that a person felt was suited to his or her interests, particularly a manual craft. It is time, however, that we return to the original meaning of the word, for it comes much closer to the idea of a Life’s Task and mastery.

The voice in this case that is calling you is not necessarily coming from God, but from deep within. It emanates from your individuality. It tells you which activities suit your character. And at a certain point, it calls you to a particular form of work or career. Your work then is something connected deeply to who you are, not a separate compartment in your life. You develop then a sense of your vocation.

Finally, you must see your career or vocational path more as a journey with twists and turns rather than a straight line. You begin by choosing a field or position that roughly corresponds to your inclinations. This initial position offers you room to maneuver and important skills to learn. You don’t want to start with something too lofty, too ambitious—you need to make a living and establish some confidence. Once on this path you discover certain side routes that attract you, while other aspects of this field leave you cold. You adjust and perhaps move to a related field, continuing to learn more about yourself, but always expanding off your skill base. Like Leonardo, you take what you do for others and make it your own.

Eventually, you will hit upon a particular field, niche, or opportunity that suits you perfectly. You will recognize it when you find it because it will spark that childlike sense of wonder and excitement; it will feel right. Once found, everything will fall into place. You will learn more quickly and more deeply. Your skill level will reach a point where you will be able to claim your independence from within the group you work for and move out on your own. In a world in which there is so much we cannot control, this will bring you the ultimate form of power. You will determine your circumstances. As your own Master, you will no longer be subject to the whims of tyrannical bosses or scheming peers.

This emphasis on your uniqueness and a Life’s Task might seem a poetic conceit without any bearing on practical realities, but in fact it is extremely relevant to the times that we live in. We are entering a world in which we can rely less and less upon the state, the corporation, or family or friends to help and protect us. It is a globalized, harshly competitive environment. We must learn to develop ourselves. At the same time, it is a world teeming with critical problems and opportunities, best solved and seized by entrepreneurs—individuals or small groups who think independently, adapt quickly, and possess unique perspectives. Your individualized, creative skills will be at a premium.

Think of it this way: What we lack most in the modern world is a sense of a larger purpose to our lives. In the past, it was organized religion that often supplied this. But most of us now live in a secularized world. We human animals are unique—we must build our own world. We do not simply react to events out of biological scripting.
